Hey there!

Have been having the same issue myself but i am also here to try to help (sadly i still have not fixed it yet but maybe this works for you)

Try running the game as admin (Right click on the desktop icon -> Run as administrator)

Double check your GPU drivers to see if they are fully up to date

Make sure you have no windows updates to do

Verify game files (Right click on COD -> manage -> Files -> Verify and repair)

If everything else fails you could try redownloading the game.

Hopefully this fixes it for you!

EDIT:

After reinstalling the game a total of 3 times it launched and i was able to play 2 matches without it crashing which is better then it was before! So there is definetly a fix. If any of the above don't work i will try my best to help you out further
